An Economic Evaluation of the Street Infrastructure Improvement for Elderly People by means of Contingent Valuation Method :

本研究旨在探讨条件价值评估法在中央商业区老人街道基础设施改善案例中的资讯与嵌入偏差。在一个典型的条件估值调查中，嵌入效应表征了受访者提供与调查中指定的商品不同的WTP（支付意愿）估计的情况，可视化了比所描述的商品更多或更少的包容性。本文采用实验性条件评估法调查，结合高级模拟器的使用，体验70岁老年人的身体残疾，探讨模拟器体验对老年人的影响，明确高级模拟器的作用，以找到合理的支付意愿估计。

The purpose of this study is to examine the information and embedding bias of contingent valuation method in the case of street infrastructure improvement in the central business district for elderly. In a typical Contingent Valuation Survey, embedding effect characterizing the situation in which respondents provide WTP (willingness to pay) estimates for a commodity different from that specified in the survey, visualizes something more or less inclusive than the commodity described. In this paper, we adopt an experimental contingent valuation method survey combined with the use of senior simulator, which enables us to experience the physical disability of the 70 yearold, to discuss the effects of simulator experience on elderly and identity the role of senior simulator in order to find the reasonable WTP estimates.
